EASTL Files

Welcome to the 3.18.00 release of EASTL. Thank you to everyone who's contributed to this release.

Feature additions and standard updates:

• Implemented eastl::bit_cast.
• Implemented eastl::is_nothrow_invocable.
• Implemented eastl::to_underlying.
• Implemented LWG defect 2106: move_iterator doesn't work with iterators which don't return a reference

Bugfixes:

• eastl::invoke fixes:
• invoke now correctly deduces the function signature when invoking a member function or member data pointer on a reference_wrapper. Previously, this would fail if using arguments which were convertible to the correct type, but did not exactly match.
• invoke now correctly forwards arguments when invoking a member data pointer.
• invoke now correctly uses decay_t instead of remove_reference_t in a number of places.
• invoke_result_t no longer uses decay_t on the type being invoked.

• invoke is now constexpr.

• eastl::variant fixes:

• Fixed incorrect results from some relational operators when valueless_by_exception() is true.

• Fixed incorrect index when an exception is thrown during emplace().

• Removed assertions from some eastl::array functions in order to ensure usability in constexpr contexts.

• eastl::make_signed and eastl::make_unsigned now work correctly for enum types and volatile-qualified types.
• Containers which support find_as now support using it with keys of the same type as the container's key.
• Disallowed use of smart pointer default deleter on incomplete types.
• Fixed an issue where nodes for some data structures could be under-aligned.
• Properly supported arrays in eastl::cbegin() and eastl::cend().
• Fixed creation of zero-length spans and subspans.
• eastl::is_reference now returns true for rvalue references.
• Fixed a potential out-of-bounds memory access when sorting certain containers.

Optimizations:

• eastl::variant optimizations:
• Avoided unnecessary double index checks in variant relational operators.
• Avoided unnecessary work in valueless_by_exception() when exceptions are disabled.
• Optimized visit() for the common case of visiting a single variant.
• Removed unnecessary copies during visit().
